A Dallas man who stalked a teenage neighbor and tattooed her name all over his body was sentenced to 20 years in prison Thursday for shooting the girl's father.

Gabriel Ramirez, 23, pleaded guilty to stalking and aggravated assault after breaking into the 17-year-old girl's home in South Dallas and shooting her father multiple times.

On the day of the shooting the teen was at home with her parents when there was a knock at the door. "I tried to open the door but it was pushed into me," the teen's father testified, "right away [Ramirez] started firing." Ramirez shot the father three times before fleeing back to his home.

The father survived but needed multiple surgeries to repair his punctured liver, stomach and lung.

Ramirez was never in a relationship with the teen but tried repeatedly to contact her before the shooting, including sending her flowers for her birthday. He also got 11 tattoos of the teen's name across his chest, neck and arms -- some of which were decorated with hearts and included her birth date and address.

"[My friends] told me the most romantic thing someone can do is tattoo their name on them," Ramirez testified in court.

During testimony Ramirez blamed his infatuation on the drugs he was using. But prosecutors say he got some of the tattoos after the shooting and sent the teen and her parents multiple letters from behind bars.

"I'll do anything for u cuzz I love u," Ramirez wrote in one of the three letters he sent to the teen, "but really wen I get out and I see ur with someone else Imma act a fool no matter how it is cuzz ur my girl."

The teen chose not to testify and kept her head down throughout the trial, holding the hands of those next to her when Ramirez took the stand.

Ramirez received 10 years for stalking and the maximum sentence of 20 years for aggravated assault, which he will serve concurrently. He will be eligible for parole in nine years.
